Deliberate mistake: The large round blood spot Alex left on the side of the building was where his right hand would have been (or made to appear) and did not seem possible. Later, it was revealed that Alex had been shot below his stomach on the left side, seemingly explaining the large blood spot on the building - except Alex did not have that part of his body close enough to that area of the building.

Deliberate mistake: Due to some unknown factors (e.g, time of night), the doves' or pigeons' behavior in the boarded-up building falls short of "factual errors." Doves respond to sound and movement, so would have flown to higher spots when Alex was at the door. Doves typically roost up high, so it is questionable why they were at floor-level. If/when doves do sleep on/near the ground, they do so in a lighter mode (one eye open) and, when spooked, would have flown away at roughly the same time, not at intervals. (00:51:15)
